As of now, our player character moves at equal speed around our game, with our movement code appearing as:
To apply an afterburner-esque boost, we are going to first create a boolean and a float variable:
and then modify our movement code to include:
In this case, we modify our movement code to include a variable (_afterBurnerModifier) that is normally 1.0 and therefore does not affect our speed. If we hit left shift, that goes to 1.5, increasing our speed.
Note, while creating a bool was unnecessary to complete this, it was left in as the step will allow us to add more effects to our afterburners down the line.
